The parse fdb/nic actions funcs parse the actions and then call
actions_match_supported() for final check.
Move related check in parse_tc_fdb_actions() into
actions_match_supported_fdb() for more organized code.

There will probably be more checks, some for nic flows, some for fdb
flows and some are shared checks. Split it for fdb and nic to avoid
the function getting too big.

The driver should add offloaded rules with either a fwd or drop action.

modify_header_match_supported() should return type bool but
it returns the value returned by is_action_keys_supported()
which is type int.
is_action_keys_supported() always returns either -EOPNOTSUPP
or 0 and it shouldn't change as the purpose of the function
is checking for support. so just make the function return
a bool type.

If link aggregation is used within stack devices driver rejects encap
rules if PF of the VF tunnel device is down. This happens because route
resolved for other PF and its eswitch instance is used to determine
correct vport.
To fix that use devcom feature to retrieve other eswitch instance if
failed to find vport for the 1st eswitch and LAG is active.

Currently the sample offload actions send the encapsulated packet
to software. This commit decapsulates the packet before performing
the sampling and set the tunnel properties on the skb metadata
fields to make the behavior consistent with OVS sFlow.
If decapsulating first, we can't use the same match like before in
default table. So instantiate a post action instance to continue
processing the action list. If HW can preserve reg_c, also use the
post action instance.

FTEs are added with mapped metadata which is saved per eswitch.
When uplink reps are bonded and we are in a single FDB mode,
we could fail to find metadata which was stored on one eswitch mapping
but not the other or with a different id.
To resolve this issue use shared mapping between eswitch ports.
We do not have any conflict using a single mapping, for a type,
between the ports.

This commit moves all implementation details of struct mlx5e_rx_res
under en/rx_res.c. All access to RX resources is now done using methods.
Encapsulating RX resources into an object allows for better
manageability, because all the implementation details are now in a
single place, and external code can use only a limited set of API
methods to init/teardown the whole thing, reconfigure RSS and LRO
parameters, connect TIRs to flow steering and activate/deactivate TIRs.
mlx5e_rx_res is self-contained and doesn't depend on struct mlx5e_priv
or include en.h.

The result of __dev_get_by_index() is not checked for NULL and then gets
dereferenced immediately.
Also, __dev_get_by_index() must be called while holding either RTNL lock
or @dev_base_lock, which isn't satisfied by mlx5e_hairpin_get_mdev() or
its callers. This makes the underlying hlist_for_each_entry() loop not
safe, and can have adverse effects in itself.
Fix by using dev_get_by_index() and handling nullptr return value when
ifindex device is not found. Update mlx5e_hairpin_get_mdev() callers to
check for possible PTR_ERR() result.

Fix by destroying the send queue of a hairpin peer net device that is
being removed/unbound, which returns the allocated ring buffer pages to
the host.

====================
mlx5-updates-2021-05-26
Misc update for mlx5 driver,
1) Clean up patches for lag and SF
2) Reserve bit 31 in steering register C1 for IPSec offload usage
3) Move steering tables pool logic into the steering core and
increase the maximum table size to 2G entries when software steering
is enabled.

To prepare for next patch where we will use a non-byte
aligned mapping, change all byte counts in register
mapping to bits.
